Error: No connection factory found for type DSL/DSL

I have a Problem with my Design Studio Client Tool. I start Design Studio in BI platform mode and create a session. This works fine. Next step is to create a new application and want to use a universe which is stored on the platform, as data source.

I click on Add Data Source, choose the universe and if I go to "Edit Query Specification" I get an error, see error log.

I test it with different universes and applications, but it's just the same error. The "host file" workaround, I found in the archive doesn't help. I use Design Studio 16.1.1
